Description

The boring grab composite set

Technical field

The present invention relates to the papermaking equipment equipment technical field, be specially the boring grab composite set.

Background technology

In boring processing; Generally all need boring grab to guarantee the machining accuracy of workpiece; But anchor clamps are in clamping process, and the workpiece shape of clamping, size differ, and traditional grip device just carries out clamping to miniature workpiece; For large-scale or the shaft-like workpiece of overlength, processing is the comparison difficulty.

Summary of the invention

To the problems referred to above, the invention provides the boring grab composite set, it is fit to the large-scale or processing of the shaft-like workpiece of overlength, has practiced thrift the equipment purchasing cost, and has improved labour intensity, has guaranteed machining accuracy, and production efficiency is higher.

Its technical scheme is such: it is characterized in that: it comprises base; Be a line on the said base and arrange first grip device, second grip device; Said first grip device comprises handle, thimble, bracing frame; Said handle is fixed in said thimble end, and said thimble is fixed on the support frame as described above; Said second grip device comprises chuck, rotating shaft, and said chuck is fixedly connected with the end of said rotating shaft.

It is further characterized in that: carriage is equipped with on the support frame as described above top, and said carriage center is over against said thimble; Said carriage is the frame structure of central hollow out; Be set with copper sheathing in the said carriage.

The invention has the beneficial effects as follows that first grip device, second grip device lay respectively at the two ends of workpiece, and workpiece is carried out clamping and positioning; The carriage center of the hollow out of first grip device is set with copper sheathing over against thimble in the carriage, can reduce the friction to workpiece; Rotate the handle of first grip device simultaneously, also can finely tune, the chuck of second grip device can be located the workpiece that clamps different size size and shape; Therefore two grip devices is used; Have accurate positioning, step up characteristics such as rapid, swift to operate, it can be suitable for the processing large-scale or shaft-like workpiece of overlength, also can use the clamping miniature workpiece separately; And guaranteed machining accuracy, shortened non-cutting time, reduced input cost.

Description of drawings

Fig. 1 is a fit structure sketch map of the present invention;

Fig. 2 is that the A of Fig. 1 is to sketch map;

Fig. 3 is that the B of Fig. 1 is to sketch map.

The specific embodiment

Like Fig. 1, Fig. 2, shown in Figure 3; The present invention includes base 1, be a line on the base 1 and arrange that first grip device 2, second grip device, 3, the first grip devices 2 comprise handle 4, thimble 5, bracing frame 6; Handle 4 is fixed in thimble 5 ends, and thimble 5 is fixed on the bracing frame 6; Second grip device 3 comprises chuck 7, rotating shaft 8, and chuck 7 is fixedly connected with the end of rotating shaft 8; Carriage 9 is equipped with on bracing frame 6 tops, and carriage 9 centers are over against thimble 5; Carriage 9 is the frame structure of central hollow out; Be set with copper sheathing 10 in the carriage 9, can reduce friction workpiece.

First grip device 2, second grip device 3 lay respectively at the two ends of workpiece, and workpiece is carried out clamping and positioning, rotate the handle 4 of first grip device 2 simultaneously; Also can finely tune; The chuck 7 of second grip device 3 can be located the workpiece that clamps different size size and shape, and therefore being used of two grip devices has accurate positioning, steps up characteristics such as rapid, swift to operate; Can be suitable for the processing large-scale or shaft-like workpiece of overlength; Also can use the clamping miniature workpiece separately, and guarantee machining accuracy, shortened non-cutting time, reduce input cost.
